UNITED STATES BENJAMIN Fv SINGER, OF LANCASTER, PENNSYLVANIA.

TURBINE ENGINE.

Application led December 4, 1923. Serial No. 678,440.

To all whom, t may concern:

Be it known that I, BENJAMIN F. SINGER, a citizen of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Turbine Engines, of which the following is a specification.

This invention relates to improvements in turbineengines, and the object in the present instance is to provide an engine of the turbine class in which a plurality of jets of steam, water -or other fluid are directed to opposite sides of a rotatable member rotating on a horizontal axis.

The object of the invention is to provide a turbine that will be properly balanced at al] times and I accomplish this by means of 'these oppositely directed fluid jets and a seri-es of pockets or vanes on each vertical side of the rotatable member, which pockets or vanes are alternately arranged as between one side and the other.

The invention contemplates a simple structure comprising a rotatable member suitably mounted' in a casing and supported by a. suitable standard, the rotatable member being exposed and adapted to transmit power through the medium of a belt or otherwise, as desired.

The invention is more lully described in the following specification and clearly illustrate'd in the accompanying drawing, in which Figure 1 is a side elevational view of my device.

Figure 2 is a plan view thereof.

Figure 5 is a side elevational view of the turbine with the casing removed, showing the pockets.

Figure 4 is a sectional view through 4-4 ot Figure 3.

Figure 5 shows in detail, one of the pockets.

The turbine engine embodying the invention comprises a easing 1 having its upper side portions formed to )rovide casing heads 2 between which heads 1s mounted the rotorof the turbine, which is indicated in general by the numeral 3. Said rotor comprises a flat-sided circular web 4 and a cylindrical body 5 peripherally surrounding the web. The rotor further comprises two annular pocket members 6, one arranged at each side of the .web 4 ef the rotor.' These pocket members will presently be more speciiically described.

Inside the casing heads, 2, and interposed between them and the pocket members 6 of the rotor, are located Idises 7, forming elosures for the pockets of the rotor, and these f discs are each provided with a plurality of coiled springs 8 which bear between the discs and the respective casing heads to insure a relatively close fit as between the discs and the faces of the pocket members.

Each pocket member 6 is provided upon one face with a series of spaced bosses Q providing between them the pockets which are indicated by the numeral 6a, and the pocket members are held for rotation with the rotor This rotation is insured through the me- 'dium of a series of spring backed studs 10, the springs l0a for which are seated in the pocket members and the studs engaging sockets 11 in the web 4 of the rotor.

The casing heads 2 are each provided with inlet and exhaust openings 14-15 and the inlets are, as usual, provided with suitable fluid jet nozzles, direct-ed at such an angle that the motive 'fluid will impinge on the resisting wall oit each pocket as the rotor rotates.

In order to close the outer and inner sides of the pockets (ia, concentric outer and inner rings 16 and 17 respectively are fitted to each pocket men'lber in the manner clearly shown in Figures 3 and 4 oit the drawings, the inner edges ot' these rings or, in other words, the edges which are presented toward the center of the rotor, engaging against the face ot the annular body 6 of the respective pocket member', and the opposite or outer edges of the rings being engaged by the tace of the respective plate 7.

I-Iaving thus described my invention, I claim:

l. In a turbine engine, the combination of a support comprising two opposed casing members, and a rotatable member mounted on the support within the casing, for rotation, said rotatable member having a series ol' pockets on each opposed vertical tace, the 'pockets on one side being alternately arranged with relation to the pockets on the opposite side,.discs located between the casing and the rotatable member, and springs interposed between the casing and the discs, said casing having inlet and .eutlet openings, and a .fluid supply jet in each of the inlets 2. In a turbine engine, a support, a casing comprising two opposite portions, and a rotatable member mounted for rotation between said two portions, said rotatable me1nber comprising a central body having a plurality of indentations in its opposed faces, a pair of members seated against the said opposite faces of the central member, and spring back-ed studs carried by said pair of members and adapted to engage said indentations, a pair of discs forming closures for the open sides of the pockets, springs interposed between the casing portions and said discs, inlet and exhaust openings in the casing portions` and fluid jets for the inlets.

3. In a turbine engine, spaced, fixed casing heads, a rotor rotatably supported between the heads and comprising a cylindrical body and a circular web within the same between the opposite sides thereof, a pair of concentric rings arranged at each side of the web within the circumference of the body and between the web and the' respective casing heads, an annular pocket member arranged between the rings of each pair and having pockets presented toward the respective casing heads and closed at their inner and outer sides by the inner and outer rings respectively, means ,connecting the members with the web of the rotor for rotation therewith, motive fluid delivery means opening through each casing head, and exhaust conducting means likewise opening through each head.

1. In a turbine engine, spaced, fixed casing heads` a rotor rotatably supported between the heads and comprising a cylindrical body and a circular web within the same between the opposite sides thereof, a pocket member arranged at each side of the web of the rotor and comprising an annular body disposed against the respective side of the rotor web and connected therewith for rotation with the rotor, bosses upon the outwardly `presented side of the said body arranged in spaced relation to provide between them pockets into which the motive Huid is to be injected, a pair of concentric rings associated with each pocket member and receiving between them said bosses whereby to close the inner and outer sides of the pockets, the edges of the rings next adjacent the web of the rotor engaging against said outwardly presented face of the body of the pocket member, and the other edges of the rings being flush with the outer surfaces of the bosses, circular discs arranged one between the inner side of each casing` head and bearing against the last mentioned edges of the said rings and the said surfaces of the bosses. means holdingV the said discs stationary with respect to the casing heads and yieldably in engagement with the said edges of the rings and the said surfaces of the bosses, means for delivering motive fluid through each casing head and the respective disc to be injected into the pockets vand effeet rotation of the rotor, and an exhaust opening through each head of the casing.

In testimony whereof I afix my signature.

BENJAMIN F. SINGER.
